2017 FIAT 500E coolant

Lights
Have someone observe the operation of brake lights
and exterior lights while you work the controls. Check
turn signal and high beam indicator lights on the
instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for
coolant or other fluid leaks. If fluid leaks are suspected,
the cause should be located and corrected immediately.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 79

3. When the system is set up for your comfort level, itis not necessary to change the settings. You will
experience the greatest efficiency by simply allowing
the system to function automatically.
NOTE:
• It is not necessary to move the temperature settings
for cold or hot vehicles. The system automatically
adjusts the temperature, mode, and blower speed to
provide comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric
units by selecting the US/Metric customer-
programmable feature.
To provide you with maximum comfort in the Auto-
matic mode during cold start-ups, the blower fan will
remain on low until the engine warms up. The blower
will increase in speed and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual over-
ride features. The AUTO symbol in the front ATC
display will be turned off when the system is being
used in the manual mode. NOTE:
The system will not automatically sense the
presence of fog, mist or ice on the windshield. DE-
FROST mode must be manually selected to clear the
windshield and side glass.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheat-
ing. OAT coolant (conforming to MS.90032) is recom-
mended. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selec-
tion.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is func-
tioning properly and the proper amount, type, and
concentration of coolant is used. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper

coolant selection. Use of the air Recirculation mode
during Winter months is not recommended because it
may cause window fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes, in
fresh air with the blower setting on high. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower
speed. Do not use the Recirculation mode without A/C
for long periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves.
Leaves collected in the air intake may reduce airflow,
and if they enter the plenum, they could plug the water
drains. In winter months, make sure the air intake is
clear of ice, slush, and snow.
A/C Air Filter
The climate control system filters out dust and pollen
from the air. Contact your authorized dealer to service
your A/C air filter, and to have it replaced when
needed.

Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
CAUTION!
•Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
• Determine the condition of the road or the path
that is under water and if there are any obstacles
in the way before driving through the standing
water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., transmis-
sion, coolant, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue
(Continued)
CAUTION! (Continued)
to operate the vehicle if any fluid appears con-
taminated, as this may result in further damage.
Such damage is not covered by the New Vehicle
Limited Warranty.
• Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
POWER STEERING
The electric power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will vary its assist to provide
light efforts while parking and good feel while driving.
If the electric steering system experiences a fault that

CAUTION!(Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of
your vehicle and also allow extended mainte-
nance intervals. Do not use chemical flushes in
these components as the chemicals can damage
them. Such damage is not covered by the New
Vehicle Limited Warranty. If a flush is needed
because of component malfunction, use only the
specified fluid for the flushing procedure.
Power Electronics And Battery Thermal
Management Systems
The Power Electronics and Battery Thermal Manage-
ment Systems are completely separate and designed to
regulate temperature for the high voltage battery and
the electric components.
Power Electronics And Battery Thermal
Management Systems — Coolant Level Check
The coolant expansion bottles provides a quick visual
method for determining that the coolant level is ad-
equate. With the vehicle off and coolant at ambient temperature, the level of the coolant (antifreeze) in the
bottles should be between the bottom and top lines
marked “MIN-MAX FILL RANGE”.
As long as the vehicle operating temperature is satis-
factory, the coolant bottles need only be checked once a
month.
When additional coolant (antifreeze) is needed to main-
tain the proper level, it should be added to the coolant
bottles. Do not overfill.
Coolant MIN/MAX
242 MAINTAINING YOUR VEHICLE

Check the Power Electronics and Battery Thermal Man-
agement Systems coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable).
Maintain coolant (antifreeze) concentration at a mini-
mum of 50% Mopar Antifreeze/Coolant 10 Year/
150,000 Mile Formula OAT (Organic Additive Technol-
ogy) and distilled/deionized water for proper corrosion
protection.
Check the coolant bottles tubing for brittle rubber,
cracking, tears, cuts and tightness of the connection at
the bottles and radiator. Inspect the entire system for
leaks.
Check the front of the A/C condenser for any accumu-
lation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the condenser.
NOTE:DO NOT REMOVE THE COOLANT PRES-
SURE CAP WHEN THE COOLING SYSTEM IS HOT.
WARNING!
You or others can be badly burned by hot coolant
(antifreeze) or steam from your radiator. If you see
or hear steam coming from under the hood, do not
open the hood until the radiator has had time to
cool. Never try to open a cooling system pressure
cap when the radiator is hot.
